Senior Software Engineer - Go, K8s, Infrastructure | Up to €105k B2B + PTO & Stock | Remote (EU)


A leading software company is seeking a highly skilled Senior Software Engineer with expertise in Go & Kubernetes (under the hood, operators, controllers, etc.) to join one of the fastest-growing projects in the Cloud Native space. The ideal candidate will be a strong Go engineer with extensive experience working with cloud native technologies and infrastructure tools. Kubernetes experience is also essential, ideally low-level k8s experience.


Responsibilities:

  • Design, build, and operate backend services, Kubernetes operators, and controllers in Go across AWS, GCP, and Azure.
  • Solve infrastructure-layer problems - networking, scheduling, storage, compute, or container runtime internals.
  • Build and maintain high-throughput services (gRPC/REST) and async orchestration workflows.
  • Shape public and internal APIs.
  • Leverage and improve AI-powered development workflows.
  • Participate in design reviews, code reviews, on-call, and customer deep-dives.


Qualifications:

  • Strong backend fundamentals and production-grade coding in Go, ideally with hands-on Kubernetes internals, cloud infrastructure, or large-scale distributed systems.
  • Deep knowledge of EKS, GKE, or AKS internals, or low-level Linux experience: process internals, networking (NAT, iptables, conntrack, SDN), filesystems, or storage.
  • Familiarity with container runtimes (CRI-O, runc, containerd) or CRIU, and cloud storage depth - block storage, CSI, volume management, or filesystem internals.
  • Kubernetes or cloud-native OSS contributions a strong plus.
  • Clear English communication, self-directed, and comfortable building where there's no playbook.


Benefits:

  • Up to €105k base + stock and generous PTO package on B2B agreement.
  • Work with a team of passionate and highly skilled engineers.
  • Flexible work arrangements and a focus on results.
  • Ample time for professional development and personal projects.


This is a unique opportunity to join a cutting-edge team and be a part of something truly special.
